24      Added code to perform gradient checks for bulk formulae/atmos. state
25      (atemp, aqh, uwind, vwind).
26      NOTE:
27      This package is out of synch with c48 package.
28      The latter also has the tangent linear gradient checks.
29      Need to be merged.
30    o verification/natl_box_adjoint:
31      * added new setup: code_bulk/, input_bulk, results_bulk
32        (Experiment 2, described in README)
33        uses bulk formulae and atmos. state as control instead of
34        air-sea fluxes.
35        Performs gradient checks for first 4 elements of atemp control.
36      * changed standard verification to perform
37        gradient checks on first 4 elements on hflux control.

58    o modifications to gradient check package (Martin Losch)
59      - enable centered differences
60      - modified format of standard output
61    o bug fix for nwettile contents
62      so far assumed global sum  in first entry (1,1,k),
63      needed for global control vector
64      -> introduced new variable nwet[c/w/s]global(nr)
65    o shifts of calls to cal/exf package to be accessible
66      in MITgcm stand-alone
67    o shifted packages_init_variables before convective_adjustment_ini

96      monitoring of adjoint state.

99    o Plus: exf changes:
100      o added run-off routine
101      o additional storing needed for ustress,vstess
102        because of state-dependent quality check
103      o added missing initialisations

105    NB: - verification/natl_box_adjoint/ 240 steps run
106          * looks ok under Linux (twain.lcs.mit.edu)
107          * looks ok on MIT SUN's (fjord.mit.edu)

124      (by G. Gebbie)
125    o missing call to obcs_diags
126    o moved calls in packages_init_fixed to packages_readparms

130    o before major merges from the Scripps setup
131      here are two small updates:
132      - field swapping for surface flux controls enabled

179    o last changes:
180      * assuming path for TAF and TAMC are known (e.g. in $path)
181      * genmake:
182        - added tools/xmakedepend to circumvene shortcoming of
183          SUN's makedepend (size too small)

212      This set of changes is relevant for ECCO only.
213      The next set/tag of changes (ecco-branch-mod4)
214      should be merged into the main trunk.

287                        bi,bj loop
288      mdsio_writelocal - same as mdsio_writetile except works for local
289                         arrays
290      write_local_r? - higher-level wrapper for mdsio_writelocal

296      or genmake -DISABLE ...
297    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
298      (additional storing is now needed for case vecinv;
299      currently nothing implemented to switch this storing off
300      in case fluxform is used since no CPP flag available).
301    
302    checkpoint40pre7
303    o bug fix in dynamics.F

316    
317    checkpoint40pre5
318    o proper initialization of Adams-Bashforth time stepping
319      + uses forward step for very first step of model (iter=0)
320    o re-generated *all* output since almost all output is modified by this
321      change (sorry but we've been putting this one off for about 2 years)
322      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
323        *not* regenerated since they are already out of date and I don't
324        want to create the impression that they are suddenly working.
325    o removed KAP stuff for DEC's
326    o modified/added many .cvsignore files in */code and */input
327    o added new expt "solid-body.cs-32x32x1"
328      + this uses an alternative form of ini_curvilinear_grid.F which
329        is not necessarily any better than the current one...
330    
331    checkpoint40pre4
332    o added re-initialisations of utrans,vtrans,rtrans in
333      calc_common_factors which are crucial for TAF.

346    o Added gradient check package
347    o Added routines for passive tracer handling
348    o Added carbon sequestration sensitivity experiment
349    
350    checkpoint39
351     o Modifications and fixes to support TAMC
352       (mainly missing or wrong directives)
353     o Corrected common blocks when fooling TAMC to produce adjoint I/O
354       in addummy_in_stepping

358       cal: calendar
359       exf: external forcing
360       ecco: essential routines to control use of cal, exf

362     o disabled some packages by default in genmake
363    
364    checkpoint38
365     o see notes_c37_adj.txt

370     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
371    
372    checkpoint37
373     o mdsio.F routine split and packaged in pkg/mdsio
374       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
375        used unless genmake -disable=mdsio)
376     o allow a more precise surface-geopotential gradient for the atmosphere
377       taking into account the change in space of Alpha (=1/rho) at the surface.
378     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
379       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
380     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
381       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
382       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
383     o Time-Average diagnostics defined as a pseudo package "timeave".
384     o pickup files : old pickup (before c35) did not work with new code (c35
385       and after) unless activating 2 commented lines in initialise-varia.
386     o Non-Hydrostatic pickup file Pb fixed.
387     o bug with Rigid-lid version (since c35) fixed.
